Legacy systems can be a real hassle to keep up and running. You like what it provides and want to continue using it, but keeping it useful and supplying it with the proper components becomes increasingly difficult as time passes. And in the case of a discontinued unit such as the MFC-150CLW, that task is rendered all the more difficult by the lack of new ink cartridges being produced for it. So there you are, stuck with a multi-function device that should be covering your printing, copying, scanning and faxing needs, but you're stuck due to a lack of ink.
The MFC-150CLW needs four separate ink cartridges, one each for black, magenta, cyan and yellow toner needed to produce the colour documents that it's capable of handling. Where to find those if Brother no longer produces them? ClickInks still does. ClickInks produces their own fully compatible ink cartridges that work perfectly with the MFC-150CLW all-in-one system, so you can still get full use from the device. No need to toss it out in favor of something newer just because the manufacturer has moved on. And ClickInks also sells toner refill packs and paper for the MFC-150CLW, all backed by their same day shipping policy that gets you the supplies that you need that.
